Application filed March 31, 1914. Serial No. 828,604.

To all whom it may concern:

Be it known that I, CYRENIUS W. SILLIN, a citizen of the United States, residing at Stuttgart, in the county of Arkansas and State of Arkansas, have invented new and useful Chimney-Caps and Storm-Shields, of which the following is a specification.

The invention relates to improvements in chimney caps and storm shields.

The object of the present invention is to improve the construction of chimney cowls and to provide a simple, practical, and comparatively inexpensive chimney cap and storm shield of strong and durable construction, adapted to be readily applied to a chimney and capable of protecting the latter from rain, snow, sleet, and wind, and adapted also to prevent downdrafts and consequent smoking of a chimney.

A further object of the invention is to provide a device of this character equipped with a rotary hood or shield, arranged to be held in the wind by a blade or vane and adapted to intercept the wind and prevent the same from blowing over the chimney and choking the same.

With these and other ob ects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that various changes in the form, size, proportions and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure l is a perspective view of a chimney cap and storm shield constructed in accordance with this invention. Fig. 2 is a central vertical sectional view of the same. Fig. 3 is a horizontal sectional view of the same. Fig. 4; is a reverse plan view of the device, the bearing bracket, and the lower anchor brace being omitted. Fig. 5 is a detail view of the lower anchor brace. Fig. 6 is a detail sectional view on the line 66 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

T11 the accompanying drawings, in which is ll lustrated the preferred embodiment of the invention, 1 designates a vertical shaft or spindle arranged centrally of the upper portlon of the chimney 2 and mounted in a bearing bracket 3 and in a lower anchor brace 4:- The bearing bracket 3 comprises four legs or braces 5 consisting of lower chimney engaging portions and inclined upper portlons, and connected at their upper ends at the center of the bracket and supporting a bearing disk or plate 6 to which the legs or braces are suitably secured.

Theopposite legs or braces 5 may consist of a single piece of material, as illustrated in Fig. 2 of the drawings, but the bracket may be constructed in any other suitable manner. The lower chimney engaging portions fit against the exterior of the chimney and conform to the configuration of the same, being provided at an intermediate point with angular bends to fit around the collar or projecting portion 7 of the chimney. The said angular bends of the legs form intermediate horizontal portions which are arranged upon the collar 7 of the chimney, and the said legs or braces are equipped at their lower terminals with blocks or pieces 9 forming shoulders for engaging beneath the collar or projecting portion 7 of the chimney. The blocks 9 are spaced from the intermediate horizontal portions 8 to receive the projecting collar or portion 7 of the chimney, but the lower ends of the legs or braces 5 may be provided with any other suitable means for engaging beneath the said projecting portion 7 of the chimney. The legs or braces are clamped to the chimney by upper and lower set screws 10 and 11, mounted in threaded perforations and engaging the chimney. The lower set screws pierce the blocks 9 and by being located below the plane of the projecting portion 7, securely fasten the bearing bracket to the upper portion of the chimney. The upper set screws assist in maintaining the bearing bracket on the chimney, but they may be omitted if desired.

The vertical shaft or spindle, which is rigidly supported in an upright position with relation to the chimney, has its lower terminal 12 threaded and extending through a central opening in the lower anchor brace, to which the shaft or spindle is securely clamped by nuts 13 which engage the upper and lower faces of the anchor brace. The anchor brace, which is horizontally disposed, is arranged interiorly of the chimney and extends diagonally across the same, and it is provided with terminal arms 14: arranged in pairs, the members of each pair being disposed at right angles to each other and fitting the diagonally opposite angles of the chimney. The horizontal anchor member 4 firmly braces the lower end of the shaft or spindle and cooperates with the bearing bracket in rigidly supporting the said shaft or spindle in a central vertical projecting position.

The bearing plate 6 at the apex of the bracket 8 is provided in its upper facewith an annular ball race 15, which receives a series of anti-friction balls 16 interposed between the fixed lower bearing plate 6, and an upper rotary bearing plate 17. The up per rotary bearing plate 17, which rests upon the anti-friction balls 16, has a central opening to receive the vertical shaft or spindle, and is preferably provided at its pe riphery with a depending portion or flange which extends below the edge of the lower bearing plate to protect the ball bearing. The upper bearing plate sustains the weight of arotary hood or shield 18, designed to be constructed of stout galvanized sheet metal or other suitable material, and comprising a horizontal top portion 19 and a depending inclined portion 20, arranged at the front of .the horizontal portion and extending downwardly and outwardly therefrom to a point below the top of the chimney, and provided with a substantially vertical lower I portionQl. The hood or shield, which may be varied in sizeto suit the size of the chimney to which the device is applied, is adapted to exclude wind, snow, rain, and sleet from the interior of the chimney and the front inclined portion serves to deflect the wind upwardly to cause the same to pass over the top of the device. The horizontal top portion is riveted or otherwise secured to the upper face of a horizontal reinforcing plate 22, which is adapted to stiffen the horizontal top portion of the hood or shield and sustain the weight of a superimposed vane 23. The plate 22, which is constructed of suitable metal, may be of any desired size, and it also preferably extends rearwardly from the inclined front portion 20 to a point in rear of the shaft or spindle. The plate 22, which has an opening to receive the upper portion, is. provided with central and side rearwardly projectingarms 2 which are preferably of a length to extend to the rear edge of the horizontal top portion of the hood or shield.

The vane or blade 23, which is located in rear of the vertical shaft or spindle 1, consists of a plate of sheet metal or other suitable material, of sullicient size to maintain the front depending portion of the hood or shield positively in the wind at all times. The blade or vane, which may be of any preferred configuration, has a horizontal .loweredge and is secured between upturned flanges of a pair of angle bars 25 to which the inner side edges of the horizontal side screens 26 of a spark arrester arealso secured. The imperforate horizontal portion of the hood or shield is of a size to cover the opening of the chimney, so as to positively exclude moisture therefrom, and the side screens 26, which extend horizontally fromthe rear edge of the imperforate top portion of the hood or shield, are prefera-bly constructed of woven wire, having a mesh of a suitable size to arrest the sparks toprevent the same from ascending and endangering neighboring roofs. The side screens, which arepreferably tapered rearwardly, as shown, are provided at their outer edges with metallic binding strips 27, and their inner edges are fitted against the faces of horizontal flanges of the angle bars 25 and are securedbetween the same and upper metallic bars or binding strips 28. The front edges of the spark arrester screens are arranged at the upper face of the horizontal portion of the hood or shield, bound by a transversely disposed metallic strip 29 extending entirely across the hood or shield and connecting the side screens. The upturned flanges of the longitudinal angle bars 25 are cut away as shown, to provide a. passage for the front transverse binding strip 29, which is arranged upon the upper face .of the horizontal flanges of the said angle .bars 25.

The front metallic binding strip 29 is bolted or otherwise secured to the hood or shield. The side screens, which constitute the spark arrester, may be mounted in any other desired manner, and the vane or blade and the side screens are braced by inclined upwardl and rearwardly diverging bars or members 30 extending from the outer portions of the side screens to the upper rear portion of the blade or vane, and suitably secured to the said parts. Any other desired form of bracing may, of course, be em- M ved- The hood or shield is carried by a horizontally disposed rotary bar or member 31 provided at a point intermediate of its ends with an opening 32 for the shaft or spindle, and extending in advance and in rear of the same, and provided at its front end. with laterally extending arms 33 set at an inclination to present inclined front faces to the inner or rear face of the depending front portion of the hood or shield. The laterally extending arms are formed by a plate or piece welded or otherwise secured to the front end of the horizontal bar or member 31, and riveted or otherwise secured to the front portion of the hood or shield. The rearwardly extending portion of the horizontal bar or member 31 is provided with a longitudinal kerf or slot 34:, in which is secured a vertical post or support 35 constructed of sheet metal or other suitable material, bolted or otherwise secured at its lower end to the rear end of the horizon tal bar or member 31. The post or standard 35 extends upwardly from the horizontal bar 31 to the rear portion of the vane or blade, and its upper portion is arranged between the said vane or blade and one of the longitudinally disposed angle bars, and is secured to the vane by one or more bolts or other suitable fastening device, which pierces the upturned flanges of the angle bars 25, the blade or vane, and the post. any number of fastening devices, of course, may be employed, and the post 35, which supports the outer rear portion of the vane or blade and the outer portions of the spark arrester, may be mounted in any other desired manner. The horizontal bar or member, which rests upon the upper bearing plate, is adapted to rotate freely with the same, and the rotary portions of the device are retained in position on the upper projecting portion of the shaft or stem by upper and lower set collars 36 and 3'4", arranged at the lower face of the reinforcing plate and at the upper face of the horizontal bar 31. The set collars, which are adjustable on the upper portion of the shaft or spindle, are clamped to the same by set screws. The upper end 38 of the vertical shaft or spindle is threaded for the reception of the retaining nut 39, a washer being preferably interposed between the same and the upper face of the horizontal portion of the hood or shield.
